Is it possible to create an indistinguishable or equal frequency response between a digital equalizer and an analog emulating equalizer plug-in?

Sammanfattning: This research examines if an indistinguishable, or equal, frequency response of a software plug-in that is emulating an analog equalizer can be reconstructed using a more standard digital equalizer  such as one incorporated with a digital audio workstation (DAW). It is narrowed down to solely involve high frequency bands by analyzing the emulating plug-ins hi-shelving filters. A two-comparison forced choice ABX-test was conducted to verify the hypotheses and the results show that the difference between the original and the reconstructed hi-shelving filter was inaudible to the listening test participants. Further research and application for these findings is discussed
